SPINDLE AND BEARING THEREFOR.

SPECIFICATION forming part of Letters Patent No. 508,323,dated November 7, 1893.

Applicationiiled Tune 2, 1893. Serial No. 476.333. (No model.)

To a/ZZ whom it may concern,.-

Be itfknown that I, GEORGE W. KNIGHT, of Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Spindles and Bearings Therefor, of which the.

I5 In the invention to be herein described a.

spindle having a sleeve whirl rigidly attached thereto is employed in connection with a rigid bolster or lateral bearing, I being enabled to use such rigid bolster or bearing because I shoe, which, besides being interposed between the pintle and bearing is connected loosely by a suitable rivet or equivalent, so that the shoe rotates with the spindle in the bearing 2 5 at the interior ofthe supporting-case.

In my invention thespindle does not rotate in the shoe, but it has freedom to tip or move laterally in or with relation to said shoe to a limited extent, the it between the lower end of the spindle and shoe being preferably looser than between the u pper end of the shoe and the pintle.' vBy removing the rivet or equivalent uniting theshoe-to the pintle of the spindle,the yspindle and shoe may be separated when desired, as when a new shoe is to be applied for a worn one.v The shoe may be made of the same or a different metal from that used in the spindle, thatA is, it may be of any metal thought or found to possess superior properties for bearings,`as for instance brass or gun metal, or any of the bronzes.

In Inyinvention the bolster may tit the supporting case or outside support rigidly, suitable oil holes being provided to lead oil to the shoe, but this invention `is not limited to vholding the bolster solidly in the supportn ing case, or even totheretention of the bolster as an ,independent piece. l l Figure'l, in elevation and section, repre- 5o sents a spindle with a shoe and suitable bearhave entered thel pintle of the spindle into a ings, the same embodying one form of my invention. Fig. 2 is asection in the line Fig. l; and Fig. 'shows a tnodiiication.

Referring to the drawings, A represents aA spindle rail, it containing a supporting case B which may be attached to the rail in any usual manner, as for instance, by a nut B. engaging a thread B2 of the supporting case. The spindle C shown in Fig. 1 as having a tapering pintle c has a sleeveiwhirl C fixed 6o to the blade of or that part of the spindle which is located above the whirl bobbin adhesively. The pintle enters in Fig. l a hole made in a shoe b and .preferably there will be looseness between the pintle and the inner bore of the shoe.

The pintle and shoe in this present form of my invention, are shown as connected by a pin on one entering a slot or hole of the other, the pin, in this instance marked d, being car- 7o ried by the spindle and yentering holes d in the shoe ,the object being to connect the shoe and spindle so that the shoe will revolve with 'the spindle and receive the wear which is commonly borne by the pintle ofA the spindle. 75 For the best results,.the looseness between the pintle of the spindle and the interior of the shoe, of whatever'construction, will be sufficient to overcome injurious eects from gyration, owing to high speed of the spindle. 8o The exterior of the shoev will be properly shaped to tit its surrounding lateral support, and where the looseness above referred to occurs between the pintle and the shoe,` it is unnecessary to have any looseness between the shoe and its exterior lateral support or bearing, and consequently a rigid support may be used.

In Fig. l, the outside bearing or lateral support for the shoe is represented as a detach- 9o able bolster e, itted externally rigidly or solidly inthe supporting case, but myinvention would not be departed from if the lateral bearing for the shoe should be made as an integral part ot' the supporting case, and I 95 have shown such a modification in Fig. 3.

As represented in Fig. 1, the weight of the spindle and its load is borne by the pin el constituting a loose coupling between the pintle of the spindle and the shoe. This shoe, Ioo

`and is supported by the coupling pin d carpreferably made of a dierent metal than the spindle, as for instance, brass or gun metal, may be readily removed when worn and another one substituted in place of it, thus relieving the spindle entirely from wear, and old spindles having worn pintles may be coinpounded as shown, and be re-used to advantge by providing them with these detachable s oes.

The supporting case has, as represented, an

oil hole at y, which leads oil down into the lower portion of the case, the oil contacting with the shoe through suitable oil holes, one of which is shown at f In the modification shown in Fig. 3,1 have shown the spindle D as having a pintle D', which is substantially cylindrical, it entering a cylindrical hole in the shoe D2.

The shoe b, shown in Fig. 3 tits directly against the interior of the supporting case,

ried by the spindle, and in said figure the step d12 is a separate piece from the shoe.

yThe spindle and its connected shoe constitute `acompound spindle, wherein the portion subject to wear in running, is made detachable and renewable.

lar construction of the connection between.

iThis invention is not limited to the particutll'e pint-le of the spindle which is to carry the bobbin and the shoe,nor to the particular shape of the lpintle or to the interior ot' the shoe, nor is the invention limited to a shoe of the exact shapeshown. v

IPrior-"to this invention I am aware that a n spindle whirl has had extended upwardlyfrom A itan oil receiving tube adapted to enter the fibase of a bobbin, and that a blade adapted to icarrya bobbin has entered said tube andfbeen connected therewith above `the baud receiv- A"ing portion of the whirl by a pin,.a pintle integral with the whirl and not'connected with thebobbin carrying portion of the spindle entering a bolster suitably sustained in the'sup-r porting-case. In such plan the pintle conineeted with thewhirl wears rapidly-*,whereas v`inJ this present invention wear upon the pintle'connected with the whirl is completely obviated, `and all the wear is put upon the shoe which can be readily detached from the pintle ot'` the spindle without in any way disturbing the whirl or that part of the spindle to which the whirl is xed.

In my invention the pull of the baud on the spindle is through the whirl fixed to that part ot' the spindle carrying the bobbin, and not to the shoe as has been heretofore practiced.

Having described Imy invention, what I claim as new, and desire to secure by Letters Patent, is- O 1. A spindle having a sleeve whirl rigidly attached thereto, and adapted by its blade to carry a bobbin adhesively, combined with a supporting case having a lateral bearing, and a shoe connected only to the pintle of said spindle and interposed between the said pintle and the said lateral bearing, the shoe rotating with the spindle, substantially'as described.

2. A sleeve whirl spindle yadapted tofcarry a bobbin upon its blade, a supportingcase having a lateral bearing extehded'into the said whirl from its under side, combined with a shoe, and means to connect the spindle and shoe loosely at a point below the band-receiving groove of the whirl,the spindle n'andshoe rotating together, substantially as described.

3. A sleeve whirl spindle, and a supporting case having a lateral'bearing which is extended into the said sleeve whirl'from'fits under side, combined with a shoe intowlrich` the `pintle of the bobbin-carrying spindle is entered loosely, and with devices to connect the `said pintle and shoeloosely, to operate, substantially as described.

4. A sleeve whirl' spindle having la rigidly connected pintle, and asupportingbasediaving a lateral bearing extended into'thesaid whirl from its under side, combinedwith a shoe connected loosely with the pintle of the spindle, the lit between the extremity otithe pintle of` thespindlea-nd theshoe beingflooser than between the upper end of theshoe and the pintle within "the sleevewhirlfsubstantially as described.

In testimony `whereof I have signedl my name to this specification inthe presence of two subscribing witnesses.
